This blog is a little effort to make biotechnology concepts simplified to all the students in the degree classes from all the universities.I took the initiative to make concise and well formulated notes supported with the diagrams.I have struggled a lot in making notes and searching for the concepts by digging library books and surfing various sites. All i want is to create one place where you can look up to biotechnology notes and rely upon them as i have put up a lot of effort on them.

BEER PRODUCTION

THE VERSATILE MICROORGANISMS

Latter part of the nineteenth century can be considered the beginning of industrial food microbiology. Once it was established that certain yeast grown under certain conditions produced beer and that certain bacteria could spoil the beer; then brewers were able to understand the microbiological role and were in a position to control the quality of their products. Microorganisms have proved their versatility by exhibiting their special qualities and their role in not only in the food industry but in brewing industry as well.

We will begin with some non dairy fermentation like alcoholic beverages and vinegar.

Beer production:

Beer is an undistilled beverage produced from fermentation of barley malt by yeast especially Sacccharomyces crevisiae and S. carsibergenesis. Generally materials rich in starch like rice, wheat and maize are also added to increase the amount of fermentable sugars. They are called as ADJUNCTS.

Beer production involves four main steps:

1.MALTING

2.MASHING

3.SACCHARIFICATION

4.FERMENTATION

It’s always better to explain any industrial fermentation schematically as it gives a better view of the whole process and from examination point of view; it leaves better impact. I would suggest the schematic view but if you are comfortable with the paragraph explanations then even its perfect!!!

i have posted schematic self explanatory sketch for beer production in next post !!!

About Me

Myself a researcher interested in the field of genomics and biotechnology. Apart from following my dreams i also like to engage myself in helping other newbies in the field of life sciences. This blog is just a beginning to help budding scientists; who can get full fledged notes on biotech concepts. i have tried to make concise, thoroughly explained and supported with diagrams wherever necessary.This blog helps you avoid surfing websites for the conceptual notes. I am open to the suggestions and improvements!!! Good luck and Happy learning!!!
